Metabolic Activities

A new bioelectrochemical approach based on metabolic activities inoculated bacteria, and the microbial fuel cell (MFC) acts as biocatalysts for the natural conversion to energy of organic substrates. Among several factors, the organic substrate is the most critical challenge in MFC, which requires long-term stability. The utilization of unstable organic substrate directly affects the MFC performance, such as low energy generation. Similarly, the interaction and effect of the electrode with organic substrate are well discussed. The electrode-bacterial interaction is also another aspect after organic substrate in order to ensure the MFC performance. The conclusion is based on this literature view; the electrode content is also a significant challenge for MFCs with organic substrates in realistic applications. The current review discusses several commercial aspects of MFCs and their potential prospects. A durable organic substrate with an efficient electron transfer medium (anode electrode) is the modern necessity for this approach.

Microbial Fuel Cells (MFCs) are the special devices which are been used to produce electricity by anaerobic fermentation of organic as well as inorganic matter from easily metabolized biomass to complex wastewater using microbes as biocatalysts. Microbial Fuel Cell (MFC) is a bio-electrochemical catalytic activity of microbes to produce electricity from the oxidation of organic, substrates under natural condition. There is an increasing interest in photosynthetic MFCs designed to harness Earth's most abundant and promising energy source. Despite their MFCs havent yet successfully translated into commercial applications because they demonstrate persistent performance limitations and bottlenecks associated with scaling up. micro scale MFCs have received attention as a singular platform for various applications like powering small portable electronic elements in remote locations, fundamental studies of microorganisms, screening bacterial strains, toxicity detection in water. MFC is a great technology which can be used in the Modern World for generation of electricity and concomitant wastewater treatmentt.

Microbial fuel cell (MFC) is a device that coverts the chemical energy contents of organic matter to electrical energy by the catalytic action of microorganisms. Cow dungs as organic substrates were used in three sets of dual chambered MFCs to study the effects ofelectrodes on the open circuit voltage (OCV) generation of MFC. The anode and cathode compartments were connected using a protonexchange membrane, 1 kg of the cow dung diluted with 500 ml of water was introduced in the anode compartment of each of the setups. The electrode configurations for set-up 1, 2 and 3 respectively were Carbon-Carbon(C-C), carbon-copper(C-Cu) and carbon- zinc(C-Zn). Samples  for microbial load count were collected every two days from the anode compartment of the MFC and analyzed using standard microbiological methods. The OCV of the three setups were measured daily for two weeks using a digital multimeter. The microbial load ranged from 4.2 × 104 to 8.5 × 104 CFU/ml for bacteria and 2.1 × 102 to 2.3 × 103 CFU/ml for fungi. The range (average) of the OCV obtained from the set-ups were 0.06 to 0.72 V (0.42 V) for the C–C; 0.02 to 0.67 V (0.26 V) for C-Cu and 0.11 to 0.78 V (0.39 V) for the C-Zn. The OCV for the C-C electrode combination showed an increasing trend while the OCV of C-Cu and C-Zn showed decreasing trends with increasing number of days. The C-C electrode combination gave the best OCV. Keywords: microbial fuel cell, open circuit voltage, electrodes, organic substrate

Rapid consumption of renewable energy resources has led to development of an alternative source of energy. Fuel cell technology is a reliable and sustainable source of energy which was developed. Microbial fuel cell is a type which uses active micro-organisms as catalysts for production of electricity. The micro-organisms degrade the organic substrate to release protons and electrons which generate a potential difference across the cell. Our study focused on the generation of electricity from human urine using microbial fuel cell system. Specific bacteria were used as inoculum at anaerobic anode chamber and salt solution was supplied at aerobic cathode. The chambers were connected using salt bridge which would facilitate ion transfer. This made the system cost effective. The potential difference generated was measured using digital multi-meter.

Nowadays, Indonesia is faced with an increase in human growth, and followed by increasing electricity demand. One of the environmental friendly alternative energy that can solve this problem is microbial fuel cell, which utilizes organic matter as a substrate of bacteria in carrying out its metabolic activities to produce electricity. In this study, investigated the electrical energy produced by Microalgae Microbial Fuel Cell (MMFC) using Chlorella vulgaris and “Batik” wastewater. This study aims to assess the performance of the MMFC system based on the influence of yeast (8 g L−1 and 4 g L−1), “Batik wastewater” concentration (50 % and 100 %), and graphite electrodes (1:1 and 2:2). The MMFC system was carried out by filling anode chamber with “Batik” wastewater and the cathode with C. vulgaris. MMFC simulation was operated for 7 d. Concentration of 100 % “Batik” wastewater and 2:2 number of electrodes gave the best result in MMFC with voltage 0.115 Volt, algae absorbance 0.666. The COD decreased from 824 mg L−1 to 752 mg L−1 after the MMFC. The addition of 8 g L−1 yeast gave the optimum of bioelectricity production reached 0.322 Volt and the microalgae grew until the absorbance reached 1.031.

Abstract The present work focused on the utilization of three local wastes i.e., rambutan (nephelium lappaceum), langsat (lansium parasiticum) and mango (mangifera indica) wastes as organic substrates in benthic microbial fuel cell (BMFC) to reduce the cadmium and lead concentrations from synthetic wastewater. Out of the three wastes, the mango waste promoted a maximum current density (87.71 mA/m2) along with 78 % and 80 % removal efficiencies for Cd2+ and Pb2+, respectively. The bacterial identification proved that Klebsiella pneumoniae, Enterobacter, and Citrobacter were responsible for metals removals and energy generation. Lastly, the BMFC mechanism, challenges and future recommendations are enclosed.
